4 Claims.

1 'This'invention relates generally to plumbing fittings, and more particularly to adjustable fitting assemblies.

-Many of the 'houses built today, especially prefabricatedhouses, utilize 2 X 4" stud parti- 'tions. It has been impossible'to place properly sized waste and ventisys'tems in these partitions, as required "by federal, state'and city plumbing codes, with conventional fittings. Much difficulty has been encountered where part of the drainage system has been installed at the factory and the remainder of the fittings 'in the stack layout are installed at the site. .No adjustment has been provided in these prior fittings andv much time and 'labor has been required in the cutting and .fitting of pipe linesand fittings. Furthermorepthese prior fittings -have not been adaptable tomeet varied situations without expending a vast amount of labor at the site.

ing, Waste and/or vent fittings, and it is more .particularly an object of my invention to provide a plumbing fittingasserribl-y which is simple in construction, adaptable to a plurality of layouts, economical in cost, easy to install, and

efiicient in operation. 7

Another object of my invention is to provide a plumbingfitting assemblywhich has a maximum of adjustment of the assembled fittings.

Anotherobject of my invention is to provide a plumbing fitting assembly wherein the roughing height for all connections is adjustable.

Another object of my invention is to provide a substantially elliptical shaped drainage connection for utilization of partitions of minimum width.

Another object of my invention is to provide a plumbing fitting assembly which has emcient venting means.

Another object of my invention is to provide a plumbing fitting assembly wherein the closet and tub connections are adjustable downwardly for varying depths of floor joists.

Another object of my invention is to provide a plumbing fitting assembly which permits the use of standard length soil pipe without cutting for standard depth basements and/or the use of double hub soil pipe in exact one-half lengths to minimize pipe cutting and eliminate short scrap pieces of pipe.

Another object of my invention is to provide 2 a plumbing fitting assembly with means for attaching a pipe'stack vent. v I

Another object of my invention is to provide a plumbing fitting'assembly which has universal adaptability in one "floor 'home layouts, the {basic principles of whichmay also be applied-in multistoried structures. Another object of my inventionis to provide a plumbing fitting assembly which is especially adaptable for installation in prefabricated houses, so that work to 'be'done at the home site will be at a minimum. H

Other objects of my invention will become evident from the following detailed description, taken in conjunction with the accompanying drawings, inwhich: I i

Fig. l is a schematic plan view of my novel plumbing fitting assembly with drainage connections to a lavatory, tub, closet, and-sink;

'Fig. 2 is a side elevational view with parts broken away of an embodiment of my novel plumbing fitting assembly;

Fig. 4 is a view taken on the line i -'4 of "Fig.

2; and V p I Fig. 5 is'a'view taken on the line'5+-5 of Fig. 4.

Referring now to the drawings, Figs. '1 to 5,

inclusive, show'afitting I with anjoutwardly and upwardly extending branch portion Zfor making a water closet connection. Thefitting I "has laterally extending threaded apertures 3 forcon- 'nection to drainage lines 4 such asa drainage line from a tub or shower. The'lower en'd'of the fitting I has a spigot end 5 for 'en'gagementwith a hub 6 of any conventional *basefitting', pipe, or "an insert fitting. The upper" end I of the fitting I is formed substantially elliptical in shape as illustrated in Fig. 3 and has a hub portion 8 and an internal outwardly projecting portion 9 for centering the elliptically shaped connecting end I I of fitting Id. The elliptical shape of the connecting end portions of the fittings I and I8 is provided in order that a cross sectional area of the fittings is equal to or greater than the rounded portion of the fittings, thereby permitting the installation of this fitting in a partition of minimum Width. The upper end of the fitting Ill is internally threaded at I2 for engaging the threaded end of a pipe vent I3, which extends to the outer side of the building. The fitting Ill has laterally extending apertures I4 and I5 threadably engaging the threaded ends of drain pipes I6 and I! such as the drain lines from a lavatory I8 and a sink I9, as shown schematically in Fig. 1. It will be evident that with three threaded apertures I4 and I5 in fitting I for connections to drain pipes, my novel fitting assembly is adaptable to almost any type of installation, but it is not the intent of this application to limit the number of apertures for connection to fittings. In the conventional installation, any two of the threaded apertures I4 and I5 in the fitting I 0 will be utilized as illustrated in Fig. 1, wherein the other aperture can be closed by a screw plug as shown in Fig. 4.

It will be evident by inspection that the inlets vent above the crown of branch lines. Roughing height for lavatory and sink connections is adjustable by moving fitting I or ID longitudinally to vary the position of the elliptical end II of the fitting II] in the hub 8 of the fitting I. The closet and tub connections are also adjustable downwardly to provide for a varying depth of fioor joists wherein a longer closet flange 22 is utilized. Since the fitting I is adjustable vertically and the length of the fitting I below the fioor is so provided, standard lengths of soil pipe may be used in a standard depth basement or the spigot end 5 of the fitting I may connect directly to a conventional stack base fitting usually provided in homes without basements. The cleaning of my novel fitting assembly is simplified in that there is direct in-line access to the drainage system of the building. It will be evident that conventional adjustable connections may be disposed in the branch line 2 of the fitting I to provide for adjustment thereof.

In operation, fitting l is disposed in aperture 23 in the fioor 24 and fitting I0 is disposed above the fitting I with the elliptical shaped connecting portion II thereof in engagement with the outwardly projecting portion 9 in the elliptically shaped end I of the fitting I. The connections to the apertures 3 in the fitting I and the apertures I4 and I5 in the fitting I0 are roughed in. Connections are then made to the base hub 5 of a base fitting and all joints are caulked in conventional manner. The vent pipe I3 is then connected to the fitting III or this may bedone before the joints are caulked. Where part of the fittings and plumbing accessories are installed at the factory in prefabricated houses, fitting I may be eliminated from installation at the factory and installed at the home site with a minimum of time and labor.

It will be evident from the foregoing that I have provided a novel plumbing fitting assembly which is especially adaptable for one floor house layouts but whose principles may be adapted to multifioor layouts, which is adjustable vertically over a considerable distance to provide adapta ability in making connections for many different types of layouts, which is simple in construction and economical in cost, which has efiicient air venting, which provides a plurality of connections adaptable for any form of layout, and which is adaptable for connection to pipe fittings leading to a sewer line .without cutting and fitting of pipe. I I

Various changes may be made in the specific embodiment of my invention without departing from the spirit thereof, or from the scope of the appended claims.

What I claim is:

1. A plumbing fitting assembly comprising a fitting having a laterally extending branch portion for connection to a water closet, apertures for pipe connections and a substantially elliptical shaped hub, and a second fitting adapted for disposal in a comparatively small dimensional wall having a substantially elliptically shaped end for slip connection to the elliptically shaped hub of said first mentioned fitting, and laterally extending apertures for pipe connections.

2. A plumbing fitting assembly as set forth in claim 1, wherein said first mentioned fitting has an internal projecting portion adjacent the hub end thereof for centering said elliptical end of said second fitting in the hub end of the said first mentioned fitting.

3. A plumbing fitting assembly as set forth in claim 1, wherein said second fitting has an aperture for engaging a vent pipe.

4. A plumbing fitting assembly comprising a fitting having laterally extending apertures for connection to pipe lines, an ofi-set branch line for connection to a water closet and a substantially elliptically shaped hub with the longitudinal axis substantially normal to said branch line, and a second fitting adapted for disposal in a comparatively small dimensional wall having a substantially elliptically shaped connecting end for slip connection to said'elliptically shaped hub of said first mentioned fitting.
